Title: Cylindrical spiral gear
Inventor: OGNEV MIKHAIL EFIMOVICH
IPC: F16H1/08
Filed: 1993-06-11
Granted: 1996-01-20
Abstract: FIELD: mechanical engineering. SUBSTANCE: gear has shafts whereon a pair of inter- engaging cylindrical spiral wheels are mounted and device for unloading supports of the shafts loaded with axial force. The device is made up as a stop ridge provided with cylindrical pin and flat face perpendicular to the axis of the shaft, the pin and face being defined a step for receiving a separate part of the ridge made up as a ring-shaped member. The face of the member, which point to the wheel, is flat. The other face is conical. The inner opening is also conical. The angle between the surfaces is 90°. The face of the wheel also has outer conical surface. The angle of defining of all mentioned conical surfaces is the same and can be in the range of 30-2°. Such contact between the member with the wheel and the other part of the ridge allows the member to be self-adjusted in operation of the gear at an angle to the ridge face. This contributes to creating an oil wedge in all three zones of contact between the member with the wheel and the ridge. Radial length of the contact between the ring-shaped member with wheel and stop ridge can be changed and set depending on acceptable contact stresses. The hydrodynamic condition of lubricant and sliding of the ring-shaped member contribute to the intensified heat withdrawal from the contact zones. EFFECT: enhanced reliability. 3 dwg

Abstract: FIELD: remote control. SUBSTANCE: method provides possibility to measure rapidly varying characteristics such as vibration when validity of a priori estimation of range of measured values is low and transmission capacity of channels is limited. Method takes into account specific features of processing of measured data including integral characteristics. It involves redundant initial sampling of signals by level in order to provide wide measuring range, detection of minimal and maximal values in interval for conversion. Transform is described by equation  , where U ij-out  (U ij ) is current value of j-th measurement of i-th parameter before (after) transform; U imin  (U imax ) is minimal (maximal) value of measurement from i-th detector during interval of transform; K t  is number of sampling levels of transformed measurement. Then current transformed values of measurement with decreased bit-length are output together with extreme values for given interval with initial bit-length. EFFECT: increased functional capabilities. 2 dwg

Abstract: FIELD: information storage equipment. SUBSTANCE: method involves storing units of groups of pictures consisting of arbitrary combinations of I image encoded using information only from image, B image encoded using movement compensating estimation based on previous and/or future reference image, and P image encoded using movement compensating estimation based on previous reference image. Low-frequency data of each synchronization unit of I image are stored to each track of I image, B image and P image with spaces. High-frequency data of each synchronization unit of I image are stored sequentially in free region for I image track. P image data are sequentially stored into region which is left after storage of low-frequency I image data to tracks of P image. B image data are sequentially stored into region which is left after storage of low-frequency I image data to tracks for B image. This results in possibility of constant information output rate for special modes and decreased information losses in special modes.
